There are two different mail addresses (btw - send your real IPs and domains and mail addresses ONLY via PM!)
the one with ...law.com which points to a bgdns server (is this yours?) can not be verified as there are too many errors... but comes from a marksys.... server -> I think DNS problem!
the second with marksys... which points to a server with the IP address starting with 164.138.... (is this yours?) that is not working as the mail address is not enabled there.
So in short: the ...law.com mx is not set to the outgoing server - so you cannot receive mails using ...law.com mail addresses.
Change your DNS Settings!
send me your real server ip via pm.
If you want I can help you with it. set me some kind of admin or reseller account on your server and I will have a look.
PS.: delete the personal details from your message!!!!
